Cloud Data Integrity Verification Program Analysis

Remote data integrity verification protocol is an important technology to ensure complete data transmission and has a significant role in cloud computing technology. The paper makes analysis and conclusions on data integrity protocol, and comes up with development directions of such as fine-grained data real-time update and multi-duplicate protocol to achieve public data verification and remote authentication of multiple factor by third party. With rapid development of information technology, cloud computing has been widely applied and becomes an important technology to support information system. Since cloud computing obtain and store massive information resources and computing resources in form of remote resource access, issues on integrity and safety of cloud data in transmission are widely concerned and studied.
